The average "super-sized" fast-food meal costs only 67 cents more than a regular meal, but researchers from the University of Wisconsin-Madison found that the extra calories consumed -- about 400 on average -- could cost much more than that.
Eating extra calories regularly will result in weight gain, which, researchers say, results in higher bills for groceries, health care and even gasoline. The average "upsized" meal could result in:
5 cents more in fuel expenses (more weight reduces fuel efficiency)
35 cents more in overall food costs (heavier people eat more)
82 cents to $6.64 in added health care expenses
For every 100 extra calories a person consumes in a day, it could cost them from 48 cents to $2 when other expenses are analyzed. The researchers hope that evaluating the costs of weight gain from a financial standpoint may help people understand that upsizing a meal is often not worth it in the long run.
